Abstract

This study was conducted to promote fish paste made with white poria cocos wolf powder as a food. The tested concentrations of the powder were 0, 1, 3, 5, and 7%. All the fish paste samples had 37% water content. For the Hunter color values of samples, L-values decreased but a- and b-values increased with increasing concentrations of the powder. In addition, the folding test scores of all samples were good (AA). In the texture tests, brittleness increased where as springiness decreased with increasing concentrations of the powder. In the sensory evaluations, color, flavor, hardness, and cohesiveness scores increased, and sleekness and oily taste scores decreased, with increasing concentrations of the powder. The fish paste containing 3% white poria cocos wolf powder (3WPWP) had the highest acceptance scores for appearance, flavor, taste, texture, and overall quality. These results suggest that white poria cocos wolf powder can be applied to fish paste to increase its quality.

백복령 분말을 0, 1, 3, 5, 7%를 함유한 어묵을 제조하여 수분함량, 색도와 절곡검사, 기계적 texture, 관능검사, 기호도 검사 등의 특성을 조사하였다. 백복령 분말을 첨가한 백복령 어묵의 수분함량은 모든 시료가 37%대의 수분을 함유하고 있어 고른 분포를 띄었다. 색도 변화에서 어묵의 L값은 백복령 분말 첨가량이 증가할수록 감소 하였으나, a과 b값은 백복령 분말의 첨가량이 증가할수록 증가하였다. 어묵의 유연성을 나타내는 절곡검사에서는 모든 시료에서 AA로 측정되어 백복령 분말의 첨가에 관계없이 우수한 것으로 나타났다. 백복령 분말을 첨가한 백복령 어묵의 기계적 texture는 파쇄성은 백복령 분말 첨가량이 증가할수록 증가하였으나, 탄력성은 감소하였다. 어묵의 관능검사에서는 어묵의 색상, 향미, 경도, 응집성는 백복령 분말의 첨가량이 증가할수록 높게 나타났으나, 매끄러운 정도와 느끼한 맛은 백복령 분말의 첨가량이 증가할수록 감소하였다. 어묵의 기호도 검사에서는 3WPWP군이 외관의 기호도, 향미의 기호도, 맛의 기호도, 질감의 기호도, 전반적인 기호도 등의 모든 항목에서 가장 높은 평가를 받았다. 따라서 백복령을 첨가한 건강기능성 백복령 어묵의 가공 적성에 적절한 백복령의 첨가량은 3%가 적당하다고 사료되며 백복령을 함유한 고품질의 어묵의 제조 가능성을 확인하였다.
